vT all whom it may concern.-

Be it known that I, Vroron M. ALLEN, a

citizen of the United States, residing at,

Shinglehouse, in the county of Potter and State of Pennsylvania, have invented new and useful Improvements in. Combined Ventilators and Shades, of which thefollowing is a specification.

This invention relates to improvements in windows and the like and especially with reference to the provision of a window sash which embodies a ventilator and also embodies a shade and which can be used as a double window, a screen, a shade, .a ven= tilator, and under all weather conditions,

- and can be changed from one toanother use in an instant.

One object of the invention is to provide a window which is composed of a seriesof glass or other transparent panels WhlCh serve to admit light and which can be ad'- justed and arranged in fully opened or partially opened position to afiord ventilation.

Another object is to provide a. window sash or the like with a removable glass pane and also with glass or other transparent panelswhich may be adjusted to afiord ven tilation when the pane 1s removed or ralsed and which, when closed, and the glass pane is in place, provide a double window for winter use and which serves to protect the glass pane from frost.

Another object is to provide a window sash or the like with a glass pane and also witirlr ascreen which may he interchangeably use Another object of the invention is to provide an improved window shade which embodies bars which may be arranged either in closed position or impartially or fully opened position and which when opened or partly opened admit air and sun-light into the room and permit a person within the room to see freely out through the window and at the same time prevent a person on the outside from seeing into the room. -V7ith the above and other objects in view the invention consists in the construction, combination and arrangement of devices hereinafter describedandclaimed.

In the accompanying drawings Figure 1 is an elevation of the outer side ofa window sash constructed and arranged in accordance with my invention and showing the panels closed.

Fig. 2 is a slmilarview of the same, from the bars of the shade in open position.

Fig. 10 is a detai the holder strips in which the panel carriers are detachably pivotally mounted. Fig. 11 is a perspective view showing a modified construction of the panel adjuster. In accordance with my invention, a sash 1, door or the like is provided with a removable glass pane 2. The pane is held in a frame 3 which is preferably made of sheet metal and which extends around the edges of the pane and said frame is provided on one side with a series of ratchet teeth 4.

The upper bar 5 of the sash has an opening The lower side of the frame 3is provided with a downwardly and outwardly turned flange 7. The lower bar 8 of the sash'is provided on its upper, outer side, with a sheathing 9 of sheet metal which has an upwardly extending flange 10 over which the flange 7 of the frame 3 engages so that a tight joint is effected and rain and thelike is excluded. When the pane 2 is removed from the sash a wire screen may be substituted in its place in the sash to prevent flies and other insects from entering.

In the vertical sides of the sash, at the led elevation of one of the inner side, and showing the shade and I outer side thereof, are holder strips 11 Y which are secured by nails or screws that pass through openings 12. with which said strips are provided. The holder strips also have outwardly and upwardly inclined-slots '13 the outer ends of which are open and the lower'inner ends of which are semi-circular and form bearings. I also provide 'a series of panels 14 which may. be made of glass, celluloid or other suitable transparent material.

in the channels15 of panel carriers 16 each panel carrier being provided on its outer side near itsupper end with a journal 17 which is adapted to enter and have a bear-. .ing in one of the slots 13 of the holder asat-20. Owing to the pivotal mounting of the panels'the same may be arranged in partial overlapping relation, one above another, when closed, as shown in Fig. 3 or the panels may be swung outwardly and upwardly to open them apart to any desired .extent for ventilation and to enable air to freely enter a room through the spaces between the panels and without creating objectionable drafts. The panels being transparent freely admit light and sunshine so that they serve the purpose of glass panes as well as affording ventilation means for the window.

When the pane 2 is in place, in the window sash, and the panels 14 are closed, a double window is formed which is especially adapted foruse and is desirable in. cold weather. The panels serve to protect the glass pane as well as to confine air between them and the glass pane and also prevent .the formation of frost on the pane. The

glass pane may be partly raised if desired and may be held in any desired adjusted position toadmit air and for, this purpose I provide. a holding and adjusting dog 21 which is shown in detail in Figs. 4 and 5 and which is secured to the sash and is formed with a spring 22, a shoulder 23 to engage under any of the adjusting teeth 4 and is also formed with a finger piece 24 by means of which the dog may be disengaged from the tooth. The dog is secured to the sash by a screw 25 or other suitable device and the sash is provided with a recess 26 in which the free end of the dog operates.

The upper edge of the uppermost panel 14 is provided with a weather strip 27 which is made of rubber or the like and which is formed on the upper side with a shoulder 28 which extends longitudinally thereof and which, when the glass panels. are in closed position, closes against a flange 29 which is formed on the inner lower side of a sheathing piece 30 of sheet metal or the like which is secured on the upper bar of the sashes. The holder strips 11 are recessed in thesash so that the panels lie snugly therein when in ldachpanel has its ends fitted closed position It will be observed upon reference to Figs. 3, 6 and 7 that each panel may be readily removed through the upper ends of the carriers 16 so that either one of thepanels may be removed inde endently of and without disturbing any 0 the others. I

It will be also understood upon' reference to Fig. 10 that owing to'the provision of the slots 13 the panel carriers may be readily removed from the sash.

The connecting rods 19 of the panels are connected together at their lower ends b a cross bar 31. I also provide a connectmg rock shaft 32 which in practice is made of wire and which is arranged above the uppermost panel and is mounted in bearings 33 with which the sash is provided. Atthe ends of the shaft 32 are crank orrock arms 34 which are pivotally connected as at 35 to the upper'ends of the rods 19. Henceall of the panels are connected together and at both ends, so that the panels are all adapted for simultaneous the same extent.

I will now describe means for adjusting pivotal movement and to the panels and for locking them at any desired adjustment either when in closed or when in partly open position. A casing 36 .is mortised as at 37 in one side of the sash 44 adapted to engage in any of the notches 41 and at the opposite end of the dog is a finger piece 45 which projects slightly from the outer side of the casin A spring 46 is also provided to hold the 0g in looking position. A link 47 has one end pivotally connected to the bar 39 as at 48 and has the other end pivotally connected to one of the rods 19 as at 49. By moving the bar 39 the panels may be readily arranged either in closed or in open position, or at any desired intermediate position, and by engaging the dog with one of the notches 41 at an appropriate point the panels may be held and securely, fastened when in such adjusted position, as will be understood.

InFig. 11 I show a modified construction of the panel adjuster in which the rod 39 which is connectedb a link to one of the rods 19 is mounted or longitudinal movement in a U-shaped member 50 and is provided with a stop 51 at a point intermediate the arms of the U-shaped member. Said U-shaped member, is secured to one side of the sash 1. counteracting springs 52 are ,arranged around said rod 39 on opposite outer end of each spring bearing against one 130 of the arms of the member 50. .Hence the the hooks, however, t

panel adjuster is held yieldably by the springs and the panels are adapted to yield somewhat to the force of the wind but are normally held by the springs and the panel adjuster in closed position. By pressing outwardly on the rod 39 the panels can be arranged in open position and suitable means may be emplo ed in connection with the rod 39 to hol position. Y

On the inner side of the sash is a shade 53 which may bemade of any suitable flexible material and the upper end-of which is attached to the usual spring roller 54 which is mounted in brackets 55 of the usual construction which brackets are secured to the sash so that the shade is carried by the sash and may be raised or lowered therewith. The usual stiffenin bar or strip 56 is at the lower endof the s ade and near the lower corners of the shade are openings 57. The sash is provided near its lower corners with downwardly turned hooks 58 for engaging through said openings 57 to secure the sash and to normally hold the same in stretched condition on and across the inner side of the sash. By first disengaging the shade from c shade may be rolled up on the roller 54 as will be understood.

The shade is formed with an opening 59 which is nearly coextensive therewith and the shade is ,also provided with a series of :bars 60 which are preferably made of the "85 same material as the shade and which extend across the opening 59 and which are secured,

. as by stitching, at. their upper sides tothe.

sides of the shade as at 61. The shade bars are connected together at their ends by cords 62 and they are also'connected together at.

' their centers and lower ed es by a cord 63. The lower end of said cord is attached to the free end of an arm 64, said arm being pivotally mounted at its inner upperend as at 65 in a casing 66 which is mortised in the lower .bar 8 of the sash. A coil spring 67 is arranged around the pivot 65 and has one end attached to the arm as at 68 the other end of the spring bearing against the upper side of the casing as at 69. The spring exerts its tension to turn or move the arm 64 downwardly and thereby cause the cord 63 to. draw downwa'rdl on the centers and lower edges of the sha e bars.

also provide shade bar adjusters 70- each of which is an arm pivotally mounted as at 710m the inner side of a bracket 72. Each bracket is secured to one side of the sash and is substantially semi-circular and is provided on its'inner side with segmental serrations 73. The adjusters 70 areformed with teeth 74 to engage said serrations so that each adjuster may be securedvin any desired position, the pivots 71 adapting. the adjusters for vertical angular. movement.

the panels in open- The uppermost shade bar 60 is provided at its lower edge with a casing 75. Locking rods 7 6 are arranged for lon itudinal movement in the casing each rod aving an arm 77 at its inner end which operates in a slot 78 in the center of the casing and the outer end of each locking rod being adapted to enage in an openin 79 in one of the shade ar' adjusters 7 0. hen the rods 76 are thus engaged with the armsor adjusters 70 the en s of the up ermostshadebar are attached to said a justers 70 and hence b appropriately adjustin said bars 70 all of the shade bars may be adjusted as may be desired, to open to any extent or to an en-- tirel closed osition as desired. All of the sha e bars Wlll be adjusted to the same extent, b reason of the cord 63 by which said shade ars are connected to ether. When it is desired to roll up the sha e on its roller 54: the rods 76 must be moved inwardl and disengaged from theadjusters 70 an the cord 63 must be also detached from the arm 64 In practice the lower edges of the shade bars are stifl'ened b wires or other suitable means. The shade hers may be adjusted in the evening, when the room is li hted, so as to prevent persons on the outsi e from seeing into the lighted room. The shade can be usedin bath-room windows and also in the windows of hospitals and other like places, afi'ording privac'yand at the same time enabling light andair to enter-the room.

The panels of the window can be adjusted to afford full and free ventilation, -to exclude drafts and also to keep out dirt and storms. While I have herein hown and described a preferred form of my invention, I would have it understood that chanlges may be 'made in the form, proportion an the several parts without departing from the spirit of my invention and within the scope of the appended claims.

Having thus described my invention, I- claim 1. A window sash including a sliding unbroken pane, a plurality of pivotallymounted transparent panels wholly disposed at one .side of the pane, and when closed forming therewith a double window, and means for adjusting said panels to either open or closed position.

2. A window sash including an unbroken pane, a plurality of pivotally mounted transparent panels disposed at one side of the pane, meansfor moving said panels to open or closed position, and when closed formin with said pane a double window, 'and-sai pane being susceptible of vertical ad'ustq ment independent of the panels to a ord e'ntilation when t e panels are in opened position.

In testimony whereof I afix my signature.
